Virtualisation, a mainstay in most IT environments today, has come to represent a panacea for the data centre, eradicating a tranche of issues associated with increasing workloads and organisational growth. But it doesn’t come without its problems.
Through its inherent abstraction of physical hardware components, virtualisation maximises resources, increases data centre space and yields value from servers.Its benefits are many, including saving capex costs on physical hardware, achieving better utilisation of existing resources and better balance of performance and management.In addition, the costs for infrastructure administration and management remain within IT operations and the maximum return on the hardware investment can be achieved.
Virtual environments are intrinsically flexible, as multiple types of applications with varying operating systems can run on the same physical hardware.However, virtualisation is not without its problems. One of the major challenges CIOs should be aware of is that although virtualisation is no longer new, IT administrators still struggle to integrate storage within virtual environments.
While all storage vendors take VMware or other solutions into consideration in one way or another, there is a significant difference between the levels of integration offered. The reason is that not all storage solutions are created equal.
